B 28 transmission question

Hi all, quick question- I am not able to get to the boat for a while to look on the trans plate. Trying to determine the gear ratio for the MSA4A transmissions. I have the spec sheet which indicated the vessel had 3 options: 1,54:1 ; 1,93:1 or 2,63:1. Anyone know which of the three would be in mine? (mains are Volvo diesels TAMD 41b, props are 18 18). Thanks guys, Rex

Rex,
I have KAMD 42's with HS 1's. My ratio is 1.96/1. So I'd be willing to bet your ratio is the same.
